[closed] Geolocation question for openlayers

Hi all, I want to make a simple offline map based on openlayers and OSM. Only hard part is rightly put geolocation marker. As I want to make a fully offline map, and app can access natively to GPS service of the platform (I make it via rhomobile ),be it android or iphone. Only hard thing i need to understand how can i lets say earch 3-5seconds via ajax request lng lat of the geolocation of phone and move the marker and map also. Actually I already saw example of online geolocation, where browser detects location,but I think it's not the right thing I want to have.... Will that help me to move the marker dinamically? If no, maybe you could give an example to see ??? Any advices? Thanks beforehand
